what is function of vacuole.​

Answers

Answer 1

Explanation:

vacuoles help maintain water balance.

Answer 2

Explanation:

A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance.

In general, the functions of the vacuole include:

Isolating materials that might be harmful or a threat to the cell.

Containing waste products.

Containing water in plant cells.

Maintaining internal hydrostatic pressure or turgor within the cell.

Maintaining an acidic internal pH.

Containing small molecules.

define and describe osmosis​

Answers

Answer:

Movement of a solvent (such as water) into a solution with a higher solvent concentration by means of a semi-permeable membrane (as from a live cell), which tends to equal solute concentrations in the membrane on both sides.

Explanation:

Osmosis, the spontaneous transition, distribution, or diffusion of water and other solvents over a semipermeable membrane. In 1877, a German physiologist, Wilhelm Pfeffer, researched the process, which is important in biology.

Osmosis is the passage of water down its concentration gradient, across a semi-permeable membrane. An everyday example is a plastic wrap in your kitchen: it allows air and water vapor to move across it, but no water or food. The membranes of cells are semi-permeable, too.

Sewage discharge and fertilizer runoff is detrimental to coral growth because it increases the ________. water temperature that kills zooxanthellae water temperature that results in coral bleaching amount of toxic synthetic chemicals which stimulate excessive bacterial growth salinity of the water that results in coral bleaching amount of inorganic nutrients in the water that stimulates excessive algal growth

Answers

Answer:

The correct answer is - amount of inorganic nutrients in the water that stimulates excessive algal growth.

Explanation:

Fertilizers, sewage discharge and industrial runoff has various chemicls enrich with the inorganic compound and elements that causes eutrophication of the the water body.

Eutrophication causes increase in the number of phytoplanktons and algal growth that is stimulates by the amount of inorganic nutrients.

Thus, the correct answer is - amount of inorganic nutrients that leads to excess growth of algae.

Annette has her thyroid gland removed because of a malignant tumor. She takes synthetic thyroid hormone to replace the thyroxine that her thyroid gland would have produced, but she is worried about her blood calcium level since she has lost her source of calcitonin. Does she need to worry about this problem

Answers

Answer:

She doesn't need to worry if her parathyroid glands are working.

Explanation:

Although Annette has to worry about the impacts of thyroid gland removal and synthetic thyroid hormone intake, the calcium levels in her body need not be a concern as long as her parathyroid glands are functioning normally.

This is because the parathyroid glands are responsible for regulating calcium levels in the blood, through the production of parathyroid hormones or parathormone.

PLSSS HELLLPP- Which of the following measurements uses a derived unit? O volume O mass O length O time​

Answers

Answer:

Volume

Explanation:

volume=length ×length ×length

The metric system is the system used for the measurement. It measures the mass, length, weight, time, etc. The unit of volume is a derived unit. Thus, option A is correct.

What is a derived unit?

A derived unit is a unit used to measure and estimate the substance by using the basic or the fundamental metric unit system. It is based on units of the fundamental system.

The fundamental units include mass, temperature, time, luminous intensity, length,  electric current, and amount of substance. On the other hand, derived units result from a combination of base units.

A volume is a derived unit as it came from the fundamental unit of length as,

Volume = length × length × length

= cm × cm × cm

= cm³

Therefore, option A. volume is a derived unit.

The Channel Islands are a series of small islands off the California coast. Each island has a genetically distinct population of foxes. Compare the population of foxes on one of these islands to the population of foxes in the forests of mainland California. Which is more likely to be impacted by genetic drift? Which is more likely to be at Hardy-Weinberg equilibrium?

Answers

Answer:

The fox population on the Islands experiences genetic drift  whereas foxes in the forests has Hardy-Weinberg equilibrium.

Explanation:

The fox population on the Islands experiences genetic drift because there is no chance of introduction of different type of foxes in these Islands which experiences less variation in the population of already existing foxes. Genetic drift is the change that occur in the frequency of an existing gene allele in a population due to random sampling of organisms. Genetic drift may cause gene variants to disappear completely with the passage of time which leads to reduce genetic variation. The foxes that is located in the mainland forest experiences Hardy-Weinberg equilibrium.

) An allosteric interaction between a ligand and a protein is one in which: (3 pts) A) binding of a molecule to a binding site affects binding of additional molecules to the same site. B) binding of a molecule to a binding site affects binding properties of another site on the protein. C) binding of the ligand to the protein is covalent. D) multiple molecules of the same ligand can bind to the same binding site. E) two different ligands can bind to the same binding site.

Answers

Answer:

B) binding of a molecule to a binding site affects the binding properties of another site on the protein.

Explanation:

In an allosteric interaction between a protein and a ligand, the ligand binds to a site in the protein. As a result, there is a change in the properties of other active sites on the protein. These active-site changes may or may not allow the protein to bind to other molecules. There is a change in the protein that affects the affinity of the active site for other molecules. The affinity on the active site increases if the protein binds to an activator and decreases if the protein binds to an inhibitor molecule.
